Summary
Troubleshooting Orange.fr SMTP greeting failures in Klaviyo requires a multi-faceted approach encompassing technical configurations, sender reputation management, and understanding Orange.fr's specific policies. Key areas to address include ensuring proper EHLO/HELO configuration with matching DNS records, implementing strong sender authentication (SPF, DKIM, DMARC), managing shared IP risks, handling throttling and greylisting, and using the correct support channels for Orange.fr. A well-rounded strategy combining technical compliance and reputation building is essential for successful deliverability.
Key findings
- EHLO/HELO Configuration: Improperly configured EHLO/HELO domains, including mismatches with reverse DNS or invalid FQDNs, are a primary cause of SMTP greeting failures. A valid, resolvable domain with corresponding A and PTR records is crucial.
- Sender Authentication: Proper sender authentication (SPF, DKIM, DMARC) is essential for deliverability. Incomplete or incorrect configurations can lead to bounces.
- Orange.fr Policies: Orange.fr employs aggressive throttling, greylisting, and reputation filtering. Understanding these policies is vital for avoiding deliverability issues.
- Shared IP Risks: Using a shared IP address in Klaviyo can lead to deliverability issues due to the actions of other senders on the same IP. Negative reputation can impact your sending performance.
- Connection Limits: Orange.fr has specific requirements for simultaneous connections, which ESPs may not fully implement. Exceeding these limits can trigger throttling.
Key considerations
- Verify EHLO/HELO: Ensure your EHLO/HELO domain is correctly configured and matches your sending IP's reverse DNS.
- Implement Authentication: Configure SPF, DKIM, and DMARC for your sending domain to establish trust with Orange.fr.
- Monitor Reputation: Regularly monitor your IP and domain reputation using tools like Sender Score to identify and address potential issues.
- List Hygiene: Maintain a clean and engaged email list to minimize complaints and improve your sending reputation.
- Dedicated IP: Consider switching to a dedicated IP address to build and maintain your own sending reputation, especially if facing persistent deliverability challenges.
- Manage Connections: Implement a connection management system to limit simultaneous connections to Orange.fr servers and avoid throttling.
- Retry on Greylisting: If you suspect greylisting, retry sending the email. Note that it is difficult to determine the cause of failure on this.
- Use Correct Contact Method: Use the contact form from the postmaster orange website for support, not the abuse email address.
- Contact Klaviyo Support: If using a shared IP, inquire with Klaviyo support about the reputation of your shared IP and potential migration options.

Troubleshooting Orange.fr bounces related to SMTP greeting failures in Klaviyo involves understanding the importance of a properly configured EHLO greeting, managing sender reputation, and recognizing Orange.fr's aggressive filtering practices. When using shared IPs, the ESP is primarily responsible for managing settings, but senders must also focus on email authentication and maintaining a good reputation.
Key opinions
- EHLO Importance: A generic EHLO greeting from a shared IP doesn't provide enough sender information, increasing the likelihood of rejections. Ensure the EHLO contains a valid domain name.
- ESP Responsibility: When using shared IPs, the ESP (like Klaviyo) is responsible for managing connection limits and other technical settings, though senders are also responsible for the sending reputation.
- EHLO Configuration: A common cause of SMTP greeting failures is an improperly configured EHLO/HELO domain. Verify the domain is valid, resolvable, and has proper A and PTR records.
- Reputation Filtering: Orange.fr is known for aggressive reputation filtering. Monitoring your IP and domain reputation is critical.
Key considerations
- Proper EHLO: Ensure your EHLO greeting is properly configured with a valid and resolvable domain.
- Reputation Monitoring: Monitor your IP and domain reputation using tools like Sender Score.
- Proactive Hygiene: Engage in proactive list hygiene to maintain a positive sending reputation.
- Authentication: Implement feedback loops, manage complaint rates, and authenticate your email using SPF, DKIM, and DMARC to build a positive sender reputation.

Troubleshooting Orange.fr SMTP greeting failures in Klaviyo requires addressing multiple technical aspects of email sending. Proper configuration of EHLO/HELO domains, ensuring DNS records (A and PTR) match, implementing mutual TLS, and correctly setting up sender authentication (SPF, DKIM, DMARC) are critical. Failures typically stem from misconfigurations preventing successful handshake completion between sending and receiving servers.
Key findings
- EHLO/HELO Mismatch: SMTP greeting failures occur if the EHLO/HELO domain doesn't match the sending IP's reverse DNS.
- Mutual TLS: Server misconfiguration for mutual TLS can cause SMTP greeting failures. Ensure TLS is correctly set up.
- Sender Authentication: Proper sender authentication (SPF, DKIM, DMARC) is crucial for deliverability, and incorrect settings can lead to failures.
- DNS Configuration: The FQDN in the EHLO command must have corresponding A and reverse DNS (PTR) records; a mismatch leads to failures.
- Server Settings: The cause of a failure in your SMTP greeting is usually a problem with your server settings, hostname, or DNS configuration.
Key considerations
- DNS Records: Ensure proper DNS records (A and PTR) are configured and match the EHLO/HELO domain.
- TLS Configuration: Verify your server's configuration for mutual TLS is correct.
- Klaviyo Settings: Check Klaviyo's settings to confirm that SPF, DKIM, and DMARC are correctly configured for your sending domain.
- Hostname & Reverse DNS: Keep your server's hostname and reverse DNS record in sync.
- Handshake Completion: Troubleshoot any misconfigurations on the sending host that prevent the handshake from completing successfully.
Technical article
Documentation from RFC specifies that the EHLO command in SMTP must include a valid, fully-qualified domain name (FQDN) of the sending server. The FQDN must have a corresponding A record and reverse DNS (PTR) record. A mismatch can lead to greeting failures.
23 May 2023 - RFC 5321
Technical article
Documentation from Orange Postmaster explains that SMTP greeting failures can occur if the EHLO/HELO domain does not match the sending IP's reverse DNS or if the server is not properly configured for mutual TLS. They recommend ensuring proper DNS records and TLS configuration.
